K&N Cold Air Intake - LB7 Duramax 2001-2004

K&N 57-3034 FIPK Cold Air Intake Upgrade

The K&N 57-3034 FIPK air intake system replaces your vehicles restrictive factory air filter and air intake housing. K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engines RPM range. The 57-3034 air intake comes with a K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engines throttle body for a guaranteed power gain. The air intake system accommodates the factory mass air sensor and filter restriction gauge. The oversized round tapered air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points. The tools needed are a screwdriver, a ratchet set and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.
